Talents for Classless Books

[SaltyCoffe 73]

Every day that passes , warspear is more and more just a super end-game content with a " must " of class-less books ( more or less for any classes ) So I had an idea in mind to even improve these ones. 

We know that there are talents for the " holiday books " , for example Rage book going from 6% to 7% or Attack strength book going from 4% to 4.75% , so my idea was to create some talents that can improve the " non - holiday books " like Attack speed or Penetration book or even raid books like critical damage or critical healing. 

My idea was to create a different section for those and put for example a " 50.000 knowledge cost " for a "level-up book" talent , for example you spend 50k knowledge to make Penetration book go from 3% to 4% 
The idea was to use knowledge as it becomes useless after you maxed all your talents and you don't have to switch branches.

This would bring more ppl to invest on a book and make usage of the excess knowledge at end-game

Like a 0,5-1% increase to books from certain talents would be nice. Isn't game breaking and would allow people to min max things more. Or honestly any other way to keep knowledge relevant in the late game would be welcome. Theres really not much use for it once you have things maxed out. Being able to exchange excess kl for a token that lets you swap branches free of kl cost if you spent it would be cool too. Could sell them or stack for your own future use.
